Prenanthes aspera is easily recognized by its narrow, erect habit, unlobed, spatulate, weakly dentate leaves, basal leaves withered by flowering, heads in narrow, spiciform arrays, and densely setose phyllaries. The distribution closely matches that of the tall grass prairie, and like undisturbed prairies, this species is now rare or endangered in some states.
